How do you compost meat

GARDEN: Can I put leftovers in the compost?

GARDEN: Can I put leftovers in the compost?

I put leftover food (including cooked food, leftover meat), banana, citrus fruit, egg shells in the compost. Now I was reprimanded that only twigs, leaves, grass and other plants belong in the green waste collection. Is that correct?

First of all, the question arises as to whether the green waste is added to the in-house compost or disposed of with the green waste. If the latter is the case, the regulations of the green waste disposal / operator of the composting facility must be followed. In the Lucerne region, where the Real Community Association picks up the green waste, food leftovers in the compost are not welcome for reasons of hygiene (information available from your municipality).

Compost yourself

In principle, all organic residues from the kitchen and garden can be processed into humus by microorganisms (bacteria, fungi, algae, protozoa) and thus returned to the natural cycle. An appropriate, careful procedure is a prerequisite. It shouldn't be about disposing of green waste, but about composting. The carbon (C) -nitrogen (N) ratio, the oxygen content and the humidity play an important role. For example, wood shavings, such as litter for small animals, can be composted. For reasons of hygiene, only small animal manure from herbivorous animals should be composted. Since wood fibers hardly rot, which is related to the C / N ratio, the chips must be mixed with enough fresh material. The chopping and mixing of the raw materials and the covering of the compost are also of great importance. Microorganisms can only degrade the organic residues promptly if they have been crushed or have an interface that can be attacked. If residues get into the compost without being crushed, they are hardly decomposed, which leads to putrefaction. Microorganisms live inside the rot body, where it is damp and dark. It is therefore important that the organic residues are properly incorporated into the rotting body.

Fruit bowls

Citrus and banana peels can be composted without any problems if certain rules are followed. On the outside of the fruit peel there are antibodies that protect the intact fruit from biodegradation. If hardly any crushed fruits / peels are added to the compost, they can be badly attacked and broken down by the microorganisms.


Egg shells consist mainly of lime and are largely subject to chemical-physical weathering processes. That is why it takes a relatively long time for them to decompose. If eggshells are composted, which is quite possible, they should be crushed into small splinters and distributed in the rotting mass.

Leftovers, meat, fish

Only when the presence of rats in the area can be ruled out, nothing stands in the way of composting food waste. But here, too, an appropriate, careful approach applies. The leftovers should be mixed with some shredded material before composting and then worked well into the rotting mass. When using community compost, composting refined dishes, meat and fish is not recommended - this can quickly lead to an accumulation of residues, which results in bad smells and poor quality.
